As time passed, the aging plant was unable to keep up with increasing demands.ChallengesIn 2012, the District started working with Sunrise Engineering to find a solution that would work in their existing plant. Sunrise Engineering partnered with Aeration Industries International to upgrade the equalization basin, as well as the sludge digester/thickener.SolutionI...

Anaerobic digestion can help remove microplastics — a large cause of water pollution — during the sewage treatment process
Microplastics, or tiny fragments of plastic, include microbeads, the plastic pellets present in thousands of household and personal care products, including toothpaste, cosmetics, and beauty scrubs. They also include fragments from the breakdown of anything in our lives made out of plastic — even synthetic fabrics.
The surface of microplastic particles can host pathogenic...

For many years, hydrogen has been considered as an alternative to fossil fuels. Now, Scientists are aiming to develop an environmentally friendly method to produce hydrogen from biomass by optimizing anaerobic digestion systems.1
Climate change, dwindling fuel resources and energy prices have spearheaded intensive efforts to detect and optimize alternative fuel options. As a zero emission fuel, hydrogen is often believed to be the ultimate energy vector but despite this fact, hydrogen production can be harmful...
